This week, it's a traffic jam of interesting/worthwhile shows on a Monday night, of all things. Even if the very name makes you nauseous, there's no denying Justin Bieber's impact on pop culture. The 18-year-old Canadian heartthrob is roaming the country in support of his third studio album, Believe, which has gifted the world with Boyfriend (you'll be whispering "swag" to yourself for weeks on end) and his latest smash, As Long As You Love Me. This date also marks Bieber's Dallas debut, and unsurprisingly, sold out in short order. Don't forget your earplugs, though -- the shrill, ecstatic screaming will likely be audible from outside the building. With Carly Rae Jepsen.

7 p.m. Monday. American Airlines Center, Dallas. Sold out.

Nas and Lauryn Hill at Palladium Ballroom

On a completely different but no less anticipated note, two of hip-hop's most electrifying talents will share the stage for each artist's first Dallas performance in what seems like eons. Of the two, Nas has remained more visible and more active, releasing a steady stream of albums (his latest, Life is Good, dropped in July). Hill, on the other hand, disappeared for a time in the early '00s, has battled the IRS over charges of tax evasion and performed live infrequently. Hill is reportedly working on a new album, tentatively titled Black Rage, which would be the official follow-up to her Grammy-winning 1998 solo debut, The Miseducation of Lauryn Hill.
